seat cushion and This invention relates to a adapted for more particularly a seat cushion an automotive vehicle.

It is an object of this invention to produce that permits of great riding comfort owing to the sensitivity of its resilient cushioning effect and its come-back qualities. This has been achieved by a combination of coil springs and sponge rubber in the fabrication of the seat cushion assembly.

In` the drawing: l

Fig. 1 is a cross-sectional view of a seat cushion. l

Figs. 2 and 3 are fragmentary views showing the sponge rubber portion of-the seat cushion assembly. l

Fig. 4 is a fragmentary elevation showing the specific type of joint used in the sponge rubber portion of the seat cushion.

Referring more particularly to the drawing, the seat cushion' may be generallyreferenced 1. lThe seat cushion 1 is provided on the underside thereof with a frame 2 which forms an opening 3. The opening 3 is cov ered by a Wire mesh 4, Which wire mesh overlaps the upper face of the seat frame 2 and may be secured to the seat frame by any suitable means. The portion of the Wire mesh 4 covering the opening serves as a support for a sponge-rubber assembly which may be generally referenced 5. The portion of the wire mesh which serves'as a support for the sponge rubberis stretched taut across the opening 3 and is yieldable to a certain extent. v

The sponge rubber assembly 5 is in the form of a lattice comprising a plurality of parallel longitudinal strips 6 of sponge rubber and a plurality of transverse parallel strips of sponge rubber 7. This lattice'of sponge rubber may be moulded as an integral Whole, but preferably consists of a plurality of strips cemented together. Thestrips 6 and 7 are preferably crossed at right angles to each other and consequently the strips 6 are recessed as at 8 and the strips 7 as at 9. The recessed portions of the strips 6 and 7 are interitted to form the joints 10. The joints 10 are cemented together by any suitable rubber cement. The upper ace of the sponge rubber assembly has cemented or otherwise .OF YLEASANT RIDGE, MICHIGAN, ASSIGNOR TO GENERAL MOTORS 0F DETROIT, MICHIGAN,

suitably secured thereto the cloth 11. This sponge rubber assembly is supported by the Wire mesh 4 which covers the opening 3 within the seat frame 2.

The seat frame has mounted thereon a plurality of coil springs 12 and the sponge rubber assembly has mounted thereon a plurality l of coil springs 13, The coil springs 12 have a greater number of convolutions than the coil springs 13. The upper ends of the coil springs are secured in the Well-known manner to the upper Wire seat frame 14. The coil spring assembly is then upholstered. This \upholstery consists of the corner pad 15, the cotton pad 16, the wool pad 17 which covers the cotton pad 1G, and Wadding and the several pads are covered by, and fastened to, the trim cloth 19 which 1n turn is secured to the seat frame 2.

From the above description it is evident that there is here produced a seat cushion, the cushioning quality of which is eected by the combination of the spring cushioning qualities of coil springs and sponge rubber.

I claim:

1. A seat cushion for an automotive vehicle or the like comprising in combination a piurality of coil springs, a spongerubber portion arranged to sup ort a part of the coil springs and a cover or the said coil spring and s onge rubber assembly.

2. seat cushionfor an automotive vehicle Wadding 18. The

frame forming an opening a web covering the said opening, sponge rubber mounted on the said web, a plurality of coil sprin s a part of which are supported by the sai sponge rubber, and a covering for the said coil spring and s onge rubber assembly.

3. seat cushion for an automotive vehicle or the like comprising in combination a seat frame forming an opening, a wire mesh covering the said opening, a sponge rubber lattice mounted on the said web, a plurality of coil springs a portion of which are supported by the .said sponge rubber lattice, and a covering rubber assembly.

4. A seat cus ion for an automotive vehicle or the like comprising a seat frame, a sponge for the sald coil spring and sponge rubber lattice mounted on the said seat frame, a cloth secured to the upper face of the sponge rubber lattice, a pluralityof coil springs mounted on the said'sponge rubber lattlce and seati'rame, and a covering for` the said coil sprin and sponge rubber assembly.

5. seat cushion for or the like comprising in combination a seat `frame forming an opening, a Web covering the said opening, a sponge rubber lattice comprising a plurality of 6.
